major problem(almost solved, still need help)

OK..here I go again on my rant about not doing something unless you've got the proper tools...I know there are other ways to do things but I almost always purchase the proper tools for the job unless Im in an extreme pinch. Buying these tools can be a bit expensive but you must also realize that alot of these tools are not bike specific. Tools are always a great investment. Think of it this way. You can spend $400 for a rebuild or whatever and let the other guy pay for his tools and wait on him to finish it or you can purchase the tools, parts, and misc. chemicals/bonding agents for the same $400 and do it yourself at your own pace ( maybe 1 night / maybe 1 month idk ). Anyways then maybe your friends will be coming to you for lets say $300 a rebuild and then your off and running. Don't let the motor/gears scare you away. Its not hard with the right tools ( which inc a manual ) and you'll be proud of yourself when you accomplish it on your own. One piece of advice that I do have for you aside from the taking pictures after each step of the way, or preferably if you've got a camcorder just video taping the disassembly process stopping to point out where things go, is to use several ziplock baggies labeling each gear location, throwing the misc. nuts/washers/bolts that came from that location in there with the gear itself. Good luck and remember we are all here if you get stuck and need help!!
 
thanks regal. thats a good idea with the video of it, i think i might do that, or just take a lot of pictures. and for now, i dont have a manual, but this isnt like its my first engine job + my dad knows a ton about this kind of stuff so its not like im totaly new to this stuff.
 
You can find the manual in the DIY section here, so dont buy it on ebay! Also get the puller its so much easier! The flywheel Puller has reverse threads on it, just so you know. Spliting the case is pretty easy i would say just take your time doing it. Once you get the manual, which like i said you can download from here just follow that and you should be set.

Here is the link in DIY section for the manual

well that manuals not very specific, aculay it seems kinda crappy. does anyone know of a better one to use?

and i got an email back from the place i was going to take it in to get done and hes like yeah 7 hour job @ $85/h. its liek 600 bucks. what a load of sh*t. anyone else think 7 hours is over? i took the engine out and the head and jug off and piston and he still says 7 hours.

i took the engine out of my quad, cleaned it up, and took off the head, jug and piston in 2 hours, and thats a first time experience. theres no way. im doing it myself for sure.
 
hell, you can ebay a whole new motor for under $600. ever look into just replacing the motor completely?
 
Where you located? Id do it for $300 + parts & shipping costs. Anyways, you'll want to get the clymers manual. It has better pictures and a more detailed breakdown of all the necessary procedures for a shadetree mechanic. The manual listed here is a service manual for a yamaha mechanic who should be pretty familiar with the technics required, just requires specs and some exploded assemblies.
